Radio and Television Interference

This equipment has been tested and found to comply with CISPR EN55022 Class A, and EN50082-1 (CE) requirements and also with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case the user will be required to correct the interference at his own expense.

Changes or modifications to this equipment not expressly approved by Data Translation could void your authority to operate the equipment under Part 15 of the FCC Rules.

Note: This product was verified to meet FCC requirements under test conditions that included use of shielded cables and connectors between system components. It is important that you use shielded cables and connectors to reduce the possibility of causing interference to radio, television, and other electronic devices.

Canadian Department of Communications Statement

This digital apparatus does not exceed the Class A limits for radio noise emissions from digital apparatus set out in the Radio Interference Regulations of the Canadian Department of Communications.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux appareils numériques de la class A prescrites dans le Règlement sur le brouillage radioélectrique édicté par le Ministère des Communications du Canada.

Preparing to Use a Module

Checking the System Requirements

For reliable operation, your DT9812, DT9813, and DT9814 modules require the following:

• Windows 2000 or Windows XP (Professional Edition) operating system.

For USB Ver. 2.0 support, make sure that you install Service Pack 2 (for Windows XP) or Service Pack 4 (for Windows 2000). In addition, for some systems, you may have to disable standby mode. If you are not sure whether you are using USB Ver. 1.1 or Ver. 2.0, run the Open Layers Control Panel applet, described on

page 31.

• One or more USB ports (Ver. 2.0 or Ver. 1.1). USB Ver. 2.0 is recommended for optimal performance.

•One CD-ROM drive.

Once you have verified that your system meets the system requirements, install the software, as described in the next section.

Installing the Software

Note: Even if you already have a previous DT9812 Series module

1. Insert the ECON CD into your CD-ROM drive. If the software runs automatically (the default condition), continue with step 4.

2. If the software does not run automatically, click Start from the Task Bar, and then click Run. The Run dialog box appears.

3. In the Command Line edit box, enter D:\Setup.Exe.

If your CD-ROM is not in drive D:, enter the letter of the drive where your CD-ROM is located. The welcome screen appears.

4. Click Install Drivers and GO!

5. Click Install now!

The installation wizard appears.

6. Click Next.

The wizard prompts you for the destination location.

7. Either change the directory path and/or name using Browse or accept the default directory (C:\Program Files\Data Translation), and then click Next.

8. Click Next to copy the files.

9. Click Finish.
